Greetings,

I've only been able to select the edges of imported reference bodies, but not the edges of my extruded part. I'm trying to align the edge of the USB-C breakout with the edge of my case, but I'm unable to select that edge. The weird things is, I've gotten this to work on another, outdated version of this part after essentially extruding it from scratch. This part was generated via the split tool and then saved as its own separate part file.

The USB-C breakout is currently coincidence mated via move/copy about the right plane (running through the center) and the lipped face of my case.

Any assistance is greatly appreciated, as I'm very much a novice at SolidWorks.
